What did they just do at Gulfstream? Anybody know? Fluff up the top layers?
I do know that, aside from the surface, the turn radius, the steepness of banks (inclines), and flatness effects obviously speed, and that effects injuries (the faster they go, the more they blow apart). I know with Keeneland they changed the incline of the turns when they installed Polytrack.
